UDP <-> MQTT bridge

The goal of the bridge

The goal of this script is to receive MQTT messages from 'A' and to transform them into UDP messages that are sent to 'B' and to receive UDP messages from 'B' and to transform them into MQTT that are sent to 'A'.

Configuration of the bridge

At the beginning of the Python scripts, you can change the IP and the port of the differents actors.

Test the bridge

To test the bridge, you can use the scripts send_mqtt.sh and send_udp.sh. You just need to change the parameters at the begin of each script. To listen : mosquitto_sub -t topic -q 1 and nc -l -u -p 43000

status_reporter script

Sends RADIO_STATUS message to the UDP endpoint (APM Planner) which includes last RSSI from TX MQTT topic. It also sends a HEARTBEAT with sysid 24.

Halt button script

Listens to a rising edge on GPIO pin 16 (hardware pin, not BCM) and halts the operating system if risen.
